Thanks for the help from Andrew. I could execute loader.efi for arm64
from efi loader of my board(x-gene). Now the problem is loader can't
find 'kernel'.

loader.efi is located at part1 disk. The disk is usb removable one and
formatted as fat32 since x-gene efi loader requires it.

I have some questions...

1) What's the scheme for looking up 'kernel' from loader.efi?
2) Is there any restriction for looking up 'kernel'?

Thanks,
Jaemin
